Problems solved by technology

[0003] 1. The battery pack EA is connected in parallel with the battery pack EB. When it is charging, the battery pack EA and the battery pack EB will generate circulation loss
[0004] 2. From the connection in Article 1, it can be seen that when two sets of parallel battery packs are discharged to the load, a circulating current will also be generated between the two parallel battery packs, resulting in loss
[0005] 3. From the connection in Article 1, it can be seen that when two parallel battery packs are open-circuited without load, a circulating current will also be generated between the two parallel battery packs, and the power stored in the battery pack will be exhausted, resulting in application failure. the inconvenience

Abstract

The invention discloses a thyristor cell interface, which is composed of a first silicon controlled rectifier, a second silicon controlled rectifier, a third silicon controlled rectifier and a fourth silicon controlled rectifier, comprises a first end, a second end and a third end, and has a three-end characteristic, wherein the first end and the second end act as an interface for electrical connection between two parallelly connected cells, and the third end is electrically connected to a charging device or a load. When the cells are charged or discharged, the thyristor cell interface disclosed by the invention acts as an interface of a cell parallel connection circuit, thereby being capable of not generating loop current electric energy loss. According to the invention, electrical characteristics of a thyristor and a trigger element are utilized, and when two cell packs are required to be connected in parallel because of difference in voltage, the two cell packs can be enabled not to generate loop current by utilizing the electrical characteristics of the thyristor and the trigger element, thereby eliminating the loop current loss of the two cell packs.

Description

technical field [0001] The invention discloses a thyristor battery interface, a circuit composed of a thyristor, and a battery (Cell) is a secondary battery that converts chemical energy into electrical energy. The invention uses a thyristor circuit to electrically connect two battery packs in parallel to connect the circuit In the middle, and one of the middle ends is used as the connection interface for charging or discharging the battery; the thyristor battery interface has the characteristics of three-terminal contacts, in which the first end and the second end are electrically connected in the middle of the two battery packs in parallel, and the third end It is electrically connected to the charging device or load, and can achieve the function of connecting the battery power with the external power device. The invention can eliminate the circulation of the battery pack when the two battery packs are idle or charging or discharging in parallel, and improve battery charging....
